Interesting Notes:

Lobularia is a semi-trailing, warm weather annual and tender perennial. This compact herbaceous ornamental is native to the Canary Islands and regions along the Mediterranean, and is commonly known as Sweet Alyssum. The leaves of this variety are fine, linear, and pale green or gray-green. In late spring or early summer it becomes covered with dense, showy clusters of tiny four-petaled flowers that emit sweet, permeating fragrance which is attractive to butterflies. This variety is fast growing and floriferous. Lobularia blooms will continue through the season if conditions allow.

Purple Stream features fragrant dark purple blooms that will not fade in the sun. The breeder of this series is Danziger. It is commonly used in the landscape as ground coverage, or featured in hanging baskets and window box displays. The taller and fuller varieties go nicely as mixed fillers in the garden. Lobularia grows best in moist, fertile, well-drained soil, and is a full to partial sun exposure flower. Lobularia thrives in the heat and is easy to grow. Purple Stream will bloom all season long. Two key features of Purple Stream are heat and drought tolerance. This variety also does not require deadheading. 

Growing Tips for Homeowners:

As with every plant purchase, it is important to look for quality at the start! During the purchasing process, be sure to avoid plants that look exhausted. Finding a fresh young plant, without yellowing foliage is very important. Look for rich green foliage as indication of the plant's care thus far. This will ensure an easy start for you, and a long life for your plant.

After locating and purchasing a quality plant at the store, it is important to find the perfect place for it at your home. Lobularia is a full sun annual that thrives in the heat. The best time for planting your flower is mid-spring or early summer, after the threat of frost has passed. Be careful not to take your plant outside too early in the spring. If there is still a chance of frost in your area, keep your plant safe indoors, maintaining care in the container. Lobularia will last from late spring, through the summer, until the finish of fall. They are good pioneer plants in the garden, until other plants become more established.

Lobularia Purple Stream is a low maintenance plant that is heat tolerant. While it has a high tolerance level, water application a few times a week is still recommended, and fertilizer or compost application will ensure optimal plant performance. Be sure to apply low to the ground, near the plant’s main stem, avoiding wetting the plant’s foliage, for quick absorption and utilization. Lobularia requires a good moisture level but must be well drained. It is important to ensure good drainage in both containers and landscaping, to prevent diseases like root rot. Drainage holes, elevated flower gardens, and proper soil composition are three great ways to prevent root rot and help your plants maintain a healthy moisture level. 

These beauties will continuously bloom all season. While the plant does not require deadheading, if your plants start to look messy, feel free to trim them back to keep them tight and well shaped. After pinching back, your plant should begin to bloom again within 1–2 weeks. It is good to remove the spent flowers to encourage continued flower bud production.

Preparing the ground for your plants is always an important key to maintaining healthy plants. Pests like slugs and snails are attracted to the environment created in flower gardens and landscaping. Prevention of these types of pests includes clearing the area of holes where such pests can live. Aphids and thrips may also pose a threat to your Lobularia, but are usually taken care of by predator insects. These tiny pests usually hide on the underside of leaves and are difficult to see because of their small size.

The earliest prevention against disease and pest threat is careful examination during the purchasing process. It is important to know the difference between harmful pests and beneficial insects. Some insects may lay their eggs on your plant’s leaves in order to feed on the pests, which is actually beneficial to your flower. Lobelia flowers attract butterflies, adding a touch of beauty to your garden while promoting pollination and plant growth.
